Konstantin Boudnik commented on BIGTOP-1573:
--------------------------------------------
Will this change work with current initd bootstrap sequence?
> rpm init scripts do not wait for network
> ----------------------------------------

> Key: BIGTOP-1573
> URL: https://issues.apache.org/jira/browse/BIGTOP-1573
> Project: Bigtop
> Issue Type: Bug
> Components: rpm
> Affects Versions: 0.8.0
> Environment: CentOS 7
> Reporter: Alexander van der Meij
> Labels: build
>
> I have used Bigtop to generate a set of RPM's for the purpose of deploying
> multi-node Hadoop clusters. All the components work well, save for one
> network issue.
> It seems that the Hadoop daemons, when started at boot through their init
> scripts, do not wait for network initialisation to complete before they
> themselves are processed. As a result, when I reboot for example one of my
> datanodes, the hadoop-hdfs-datanode process is started using
> "localhost.localdomain" as its hostname - and it also advertises itself as
> such to the ResourceManager, leading to all sort of connectivity problems in
> a multi-node environment.
> I first noticed this problem when, after a reboot, I saw log files being
> created of the form /var/log/hadoop-hdfs-datanode-localhost.localdomain.log.
> When I would restart the hdfs-datanode process using the same init scripts,
> the correct /var/log/hadoop-hdfs-datanode-{fqdn}.log are created.
> I believe the problem is caused by the introduction of systemd in CentOS 7;
> init scripts are run in parallel and there are no contraints present in the
> Hadoop init scripts that instruct it to wait until network initialisation is
> complete.
> Now for the good news, adding $network to the Required-Start/Stop list for
> all Hadoop daemons solves the issue for me:
> /etc/init.d/hadoop-hdfs-datanode:
> # Required-Start: $syslog $remote_fs $network
> # Required-Stop: $syslog $remote_fs $network
